What are the Signs or Symptoms of the B2647 Code in Nissan?
The B2647 code in Nissan refers to the Electric Compressor Motor Current Limit. This code is usually triggered when the electric compressor motor draws too much current, which can cause damage to the motor and other components of the vehicle. Here are some of the signs and symptoms that you may experience if your Nissan has the B2647 code:
- Check Engine Light: The most common symptom of the B2647 code is the illumination of the check engine light on the dashboard. This light may come on and stay on, or it may flash intermittently.
- Reduced Performance: If the electric compressor motor is drawing too much current, it may not be able to operate at full capacity. This can result in reduced performance, such as slower acceleration or a decrease in overall power.
- Strange Noises: If the electric compressor motor is struggling to operate, it may make unusual noises, such as grinding, whining, or squealing. These noises may be more noticeable when the air conditioning is turned on.
- Hot Air: If the electric compressor motor is not functioning properly, it may not be able to cool the air that is being circulated through the vehicle. This can result in hot air blowing out of the air conditioning vents, even when the system is turned on.
- Battery Drain: If the electric compressor motor is drawing too much current, it may drain the battery more quickly than usual. This can result in a dead battery or difficulty starting the vehicle.
If you notice any of these symptoms in your Nissan, it is important to have the vehicle inspected by a qualified mechanic as soon as possible.

Possible Causes of B2647 Code in Nissan
The B2647 code in Nissan indicates an issue with the electric compressor motor current limit. This code is usually triggered when the electric compressor motor draws too much current, which can cause damage to the motor and other components of the vehicle. There are several possible causes of this code, including:
- Faulty electric compressor motor: The most common cause of the B2647 code is a faulty electric compressor motor. If the motor is damaged or worn out, it may draw too much current, which can trigger the code.
- Wiring issues: Another possible cause of the B2647 code is wiring issues. If there is a short circuit or open circuit in the wiring that connects the electric compressor motor to the rest of the vehicle, it can cause the motor to draw too much current and trigger the code.
- Faulty compressor control module: The compressor control module is responsible for regulating the current that flows to the electric compressor motor. If the module is faulty or damaged, it may send too much current to the motor, which can trigger the code.
- Low refrigerant level: The refrigerant in the air conditioning system is responsible for cooling the air that is blown into the vehicle. If the refrigerant level is too low, it can cause the electric compressor motor to work harder than it should, which can trigger the code.
- Malfunctioning pressure sensor: The pressure sensor in the air conditioning system is responsible for monitoring the pressure of the refrigerant. If the sensor is malfunctioning, it may send incorrect signals to the compressor control module, which can cause the motor to draw too much current and trigger the code.
If you are experiencing the B2647 code in your Nissan, it is important to have it diagnosed and repaired as soon as possible. Ignoring the code can lead to further damage to your vehicle and may result in costly repairs. A qualified mechanic can diagnose the issue and recommend the best course of action to fix it.
